Security readout for executives and security teams

This is a remote code execution flaw in Microsoft Internet Explorer 6 through 10. A user visiting a maliciously crafted website could trigger memory misuse and allow attacker-controlled code to run. The main business risk is legacy browser exposure, especially on unmanaged endpoints or old Windows systems. Exposure is most likely where Internet Explorer 6 through 10 remains installed, usable, or embedded in legacy workflows. Modern environments are mainly at risk through forgotten systems, kiosk machines, old virtual desktops, or applications that force legacy IE rendering. Treat this as a legacy-exposure cleanup priority. It is serious because the impact is code execution through browsing, but urgency depends on whether IE 6 through 10 still exists in the environment. Mitigation focus: Review Microsoft MS12-077 guidance for applicable updates and affected configurations.; Remove or disable Internet Explorer 6 through 10 wherever business processes allow.; Isolate legacy systems that cannot be upgraded from general web browsing..
